Abstract

L'invention concerne un four de fusion, à sole et de finition (14) et un procédé de production de fer/d'acier à l'aide dudit four de fusion, à sole et de finition. Selon ce procédé, la surface réfractaire de la sole (13) est enduite de conditionneurs de sole carbonés et de composés réfractaires et chargée d'éponge de fer métallique. Cette éponge de fer métallique est dressée, chauffée jusqu'au point de fusion puis mise en réaction avec du carbone et un gaz réducteur, jusqu'à ce que tout oxyde de fer résiduel soit transformé en fer à faible teneur en soufre. Des scories naissantes se séparent du fer fondu en formant des granules de fer cémenté. Ces granules sont refroidies puis déchargés, avec les conditionneurs de sole et les composés réfractaires, sur un écran (80) qui sépare les granules de fer des conditionneurs de sole. Ces conditionneurs de sole sont recyclés et les granules de fer sont soit préparés pour la vente ou en vue d'un traitement supplémentaire, tel qu'un processus d'alliage dans un four de fusion final (96).
